I've only really read the abstract and then skimmed for: > Each of the arrays has its own hash function h_i If that's what you're objecting to, isn't it just that your 'append a new salt and then hash' is a hash function h_i where i is the salt and h the 'original'/underlying hash function? I don't think it means go looking for an array of well-known named hash functions like [md5, sha1, sha224, sha256, ...].
